Two people. Eighteen accounts spanning checking, savings, credit cards, investments. Three currencies. Twenty minutes of work every week. One net worth number I actually trust. The payoff: A single, …

In 1958, Mao ordered every village to produce steel. The steel was useless. The crops rotted. Today's top-down AI mandates are producing the same pattern: ba...
A short story about debugging and how sometimes what's true is false. Starring everyone's favourite uncle, Undefined Behaviour.
When I was a kid , computers weren’t coddled and left running 24/7, when you were done with them you switched them off, and when you wanted them again you just switched them on and within a second or so they’d be loading whatever was in their disk drive.
I ran a pairwise-choice experiment on my Greyhound to rank his favorite treats, measure side bias, and accidentally turn bedtime snacks into a statistics problem.
Lix is a version control system you import as a library. It records semantic changes to enable diffs, reviews, rollback, and querying of edits.
In the previous part of the Build A Basic AI Agent From Scratch series, we added the essential tools to our agent to allow it to work…
We pulled dozens of AGENTS.md files from across our monorepo and measured their effect on code generation. The best ones gave our coding agent a quality jump…
How we're integrating CoMaps with other FLOSS apps
An aggregation is some kind of summary of a set of data. This can be the sum, length, minimum, etc. It is quite common to want to calculate such a summary repeatedly, e.g. “the maximum noise level in dB for the past 30 seconds” for a nuisance detector. In such a case we say there is a sliding window over our data, and…
A rough start to what would later become one of my favorite tech ads from the 80s.
An in-depth overview of some of the unusual and very advanced technical tricks used in the Commodore 64 game, Seawolves.
A hands-on introduction to elliptic curve cryptography. Start with curve geometry, build point addition and scalar multiplication, see why ECDLP is hard, and then use that math in ECDH, ECDSA, and ECIES.
CVE is a database used for categorizing and reporting security vulnerabilities in software. There are various kinds of vulnerabilities that can be reported. Some of them are caused simply by bugs in the program logic (like a recent CVE reported in Cargo), but some of the most nasty ones are caused by memory unsafety…
Pulling together disparate thoughts from two weeks wandering around SF
Why I swapped GNU stow's symlink farm for chezmoi: one command to bootstrap a Mac with Homebrew packages and macOS settings, a small daily sync loop, and agent skills shared between Claude Code and Codex.
After quite a long while, Hyprland 0.55 is upon us! This is an enormous update by each measurable metric - commits, contributors, features and changes.
macOS 15 Sequoia had a hard time with CoreStorage – and thus encrypted HFS+ volumes – since it deprecated both technologies and callously crippled some important tools for working with them, but nonetheless it mostly still worked. While I’d often – but not always – have to manually unlock one of my HFS+ volumes – but…
This is a long article, so I've broken it up into a series of posts, listed below. You can also read the full work as a PDF or EPUB .
When to reach for a well-known URI — and the traps that catch most protocol designers.
Mimicking the operation more accurately.
Decommissioned enterprise tesla GPUs are widely available and extremely cheap. In this post, I benchmark tesla GPUs to see if they are useful
One year minus one week ago to the day I published an article announcing the new Scheme implementation I was writing, scheme-rs . Today I am excited to announce that scheme-rs has reached its first version, 0.1.0 . You can check it out at it’s website ( scheme-rs.org , which should be updated to scheme.rs at some…
Claude Code Security is one step towards our goal of more secure codebases and a higher security baseline across the industry.
